Just to throw it out there, I noticed this when my account was hacked and coins manipulated (sold into BTC< but they were unable to withdraw).

I changed my password and created a ticket.  My ticket was never answered and it was many days the site was still up after I noted and reported this.

Unfortunately, if this was indeed a hack issue, it's unfortunate as there seems to have been ample oppurtunity to detect and correct the issue.
